Operation Manual

Attribute byte 2:
If you want to use proportional spacing you will have to define the
print start position and the number of columns to be printed as
well.
If you use start position 3 and 5 half dots character width, the
columns 3,4, 5, 6 and 7 will be printed. Attribute byte 2 would then
be 53.

Positions marked with x and values outside this table are not valid.
The only exception is
the value 0, which can be used to select fixed
spacing.
In
order to use the DLL in proportional mode you must specify
proportional mode using ESC Pl before printing. In non -
proportional
mode the characters will be printed in full width,
attribute byte 2 will then be ignored.
Since
the character we want to design will be a non-proportional
descender character, this is the command:
CHR$(27);" = ";CHR$(15);CHR$(0);CHR$(20);CHR$(64);CHR$(128);
CHR$(0);
